Answer:
a)
<u>The angle formed by intersecting chords is half of the sum of the intercepted arcs:</u>
- 1/2(mST + mPR) = m∠PUR
- 1.2(74° + mPR) = 77°
- 74° + mPR = 2*77°
- mPR = 154° - 74°
- mPR = 80°
b)
<u>The angle formed by two tangents is the half of the difference of the intercepted arcs:</u>
- m∠PSR = 1/2(mPTR - mPR)
- m∠PSR = 1/2(247° - (360° - 247°))
- m∠PSR = 247° - 180°
- m∠PSR = 67°

(1) The correct answer is: Pressure = P = 70 N/m²
Explanation:
Pressure is force per unit area. Mathematically, we can write Pressure as follows:
</span>

<span> --- (1)
Where P = Pressure = ?
F = Force = 140N
A = Area = 2.0m²
Plug in the values in (1):
P = 140/2.0
P = 70 N/m²
(2) The air particles in the inflated balloon are in chaotic motion. They are moving randomly and colliding with each other and with the inner wall of the balloon, exerting pressure on the wall of the balloon. Furthermore, they are far apart from each other, which is why when you squeeze the balloon, its shape changes accordingly as long as you are putting pressure on it while squeezing. </span>
Answer:
Angle bisector
Step-by-step explanation:
Find the measure of the angle COA. By angle addition postulate,

From the diagram,

then

Find the measure of the angle BOA. By angle addition postulate,

From the diagram,

then

Find the measure of the angle COB. By angle addition postulate,

From the diagram,

then

This means, the measures of angles COB and BOA are the same and are equal half the measure of angle COA, so angles COB and BOA are congruent. This means, the ray OB is the angle bisector of angle COA
